To all whom it may concern:-

Be it known that I, CHARLES FRANCIS JENKINS, a citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented certain new and .useful Improvements in Foldin Boxes, of whichthe following is a specification, reference-being had therein to theaccompanying drawing. 7

The general object of this invention is to produce a box structurehaving all its parts connected and adapted to lie flat when not desiredfor use, and to be folded into the form of a closed box, preferablyself-sealing, when desired.

The invention, although not limited, is more especially intended forproducing paper boxes for small articles or merchandise 'or materialsusually delivered in cartons,

where hermetic scaling is not essential, and where it is .desirable tohave somewhat greater strength and durability under rough handling thanare found'in ordinary cartons, and where at the same time convenience inuse and lowcost are indispensable' In the accompanying drawings:Figure 1. shows the entire structure in fiat form. Fig. 2 is a sectionon the line 22, Fig. 1. Fig. 3 is an end view of the closed box. 'Fig. t

i is a section on the line 4-4=, Fig. 3. Fig. 5

is a front elevation of the closed box. Fig. 6 is a perspective viewshowing a modification of the flat sheet. Fig. 7 is a section betweenthe ribs of Fig. 6. Fig. 8 is a perspective View of a modification ofthe corrugated member shown in Fig. 6.

In these views, A represents a sheet of heavy paper or paper board after.it is formed by creasing it transversely at A, A to divide it'intorectangular sections A A A A A, which are to serve as the sealing flap,the top, theside, the bottom, and another side, respectively, of thecomplete box, and further formed by embossing each section, except theflap, to form parallel, slightly separated ribs, B, B near and parallelto the parallel free margins of the several sections. The ribs arepreferably beveled at each end so that when adjacent sections are sofolded as to be perpendicular to each other, the beveled ends of theribs are pressed together. In order that the ribs may be 'held againstspreading or flattening, and to form strong hinges between the sections,as well as to bind the box at each end and 1mprove its appearance,textile tapes or strlps F of tough paper wide enough to cover thegrooves, are cemented to the margins of the sheet A.

The ends of the box are plates 0, each of which is secured to one of thesections by a hmglng strip D in such manner that the end may lie fiatupon the section as shown in Fig. l, or may be swung to perpendicularposition and thereby have its hinged edge seated in the space or groovebetween the adjacent ribs. In this latter position each end lies in theplane of the corresponding grooves in the other sections, and when thelatter are properly folded the remaining margins of the end are seatedand securely held in the corresponding grooves, the seating being aidedby the rounded form of the ribs. The goods to be inclosed may be placedin the, box before the cover is folded down, and the cover being closed,the package may be sealed by moistening and pressing down the flap,WhlCh is provided with gum at E.

In Fig. 6 I have shown the modification of omitting the tapes or stripsand the embossing of the sheet A and securing to the face of the sheetstrips G of paper or equally rigid material provided with ribs Ganalogous to those of the other figures and similarl located withrespect to the margins of the sheet, the latter in this case being aplane sheet simply scored or grooved along the folding lines. If thestrip G be of paper, it is conveniently secured to the sheet by paste,but if it be of metal it may be formed with tongues or spurs H or I, asshown in Figs. 7 and 8.

What I claim is:

l. A folding box body consisting of a paper sheet weakened alongparallel bending lines and having near each margin transverse to saidlines two slightly separated, parallel embossed ribs adapted to receiveand hold,

between them, box end pieces, when the sheet is folded to box form.

2. A folding box having a body sheetend to end 'of the same, andspanning, re- I gle paper sheet weakened along parallel bending linesand embossed to form near each margin transverse'to said lines twoparallel end-retaining ribs each notched at the folding lines,substantially as set forth.-

4. A box body sheet having on one face near each of two opposite marginsan endreceiving channel and u on the corresponding parts of its oppositeFace permanently attached bands transversely bridgin the entire channelformation, substantia ly as set forth. I V

In testimony whereof I afiix my signature in presence of two witnesses.
